Farmer Phill Everest (third from right) addresses the field day on his farm.
The Everest family of Ashburton in Hinds are one of many local farming families working hard to reduce nitrogen loss.
Phill and Jos Everest farm 750 dairy cows with their son Paul and his partner Sarah, and they work together as a family to meet their environmental goals and stay ahead of regulations.
Phill and Jos are actively involved in DairyNZ's Meeting a Sustainable Future project, which shares knowledge among local farmers to reduce nitrogen loss.
Phill is a DairyNZ Climate Change Ambassador and says local farmers know they need to make changes for the future to protect the environment.
"We've always focused on learning how to do things better. We’ve got to learn fast to make changes and keep contributing to our local communities.”
The family’s changes include reducing nitrogen fertiliser by 35% – ahead of the national and regional deadlines. This resulted in a small reduction in milk production this season.
Phill says they learnt from the changes and next season will adjust their approach and focus on improving pasture growth to lift milk production.
“We developed an annual nitrogen application plan so we knew what our target application rates were each month to meet the new targets. We also used a coated urea product which reduces greenhouse gas and nitrogen losses,” says Phill.
Among other improvements, the Everests have installed a variable rate irrigation system on one pivot irrigator. This is very water efficient and allows water to be applied in different amounts across a paddock, reducing drainage and nutrient losses.
The farm team has carried out 22km of planting along drains and fence lines to improve water quality and provide shelter.
Plantain and chicory have been added to their pasture mix, and additional plantain and clover seed is applied with capital fertiliser dressing. These changes help reduce nitrogen loss.
Together with DairyNZ, the Everests hosted a field day in May on their farm near Ashburton, which 45 farmers attended.
Phill says reducing nitrogen losses further to meet environmental requirements will be a significant challenge for their family and other farmers.
OPINION: In the 1980s, concern was expressed in West Germany about the falling birth rate. Some simple analysis was performed by Professor Helmut Sies, physician and biochemist at Dusseldorf University. His letter ‘A new parameter for sex education’ was published in Nature in 1988:
OPINION: Dairy farmers know better than anyone that change is constant.
A four year trial has reaffirmed that mixing plantain into dairy pastures can help reduce nitrogen losses to freshwater while maintaining milk production and profitability, say researchers.
OPINION: Today marks Farm Worker Appreciation Day – a day we’re proud to recognise here in New Zealand.
OPINION: Mike Chapman, former chief executive of levy-funded HortNZ, has thrown out a challenge to farmers and growers to put their levy-funded industry organisations under the same scrutiny as fertiliser, electricity, labour and freight.
OPINION: The time has come for the Government to back the organic sector.
Plan ahead and be patient. That’s the message to farmers and horticulturalists from the chairman of the NZ Agricultural Aviation Association, Kent Weir.
The industry is crying out for graduates with agricultural related degrees.
While GPS and guidance have become the norm and yield mapping and variable application continues to gain traction, most agricultural machinery manufacturers continue to expand their technology offerings, amalgamating the vast amounts of data being collected to streamline real-time and ongoing management decisions.
Supply chain problems, growing protectionism and a move to greater food security are some of the key challenges facing New Zealand exporters, according to our top trade negotiator, Vangelis Vitalis.
Celebrating 50 years in the rural landscape of Central Canterbury and beyond, Ashburton-based Carrfields, has been the exemplar for all aspects of modern agriculture via its extensive range of services including supply, growing, agronomic advice and marketing.

OPINION: With fuel prices soaring, one would have expected most farmers to be reclaiming excise duty on petrol.
